Abstract

In the formulation of Jarrett and Shimony, Bell inequalities follow from three assumptions: measurement independence (MI), parameter independence (PI), and outcome independence (OI). We have recently demonstrated that the conflict between quantum theory and hidden variables extends far beyond Bell’s theorem. Quantum theory violates inequalities even when MI and PI are simultaneously and arbitrarily relaxed (except for a complete relaxation), as well as inequalities where OI is arbitrarily relaxed (again, except completely). We will discuss the implications, experimental tests, and potential applications of these results.
